Does TETRA1 handle data?
• Database look up• AVL• Email• File transfer• Limited slow
scan video• But some multimedia
applications could ask for more….
TWC2005 – November 2005November 05 - TETRA World Congress 2005
Mission Critical Data Applications on TETRA• Today’s applications need data capacity
– Frequent messages, small payload:• AVLS from portables and vehicles• Database access• Status messaging
• But some applications starting to need more data throughput– Less frequent messages, much bigger payloads
• Mug shots• File transfer• Slow scan video

TETRA2 brings new capabilities … to Fire Check floor plans of burning buildingTETRA 1Database of plans held on local CD in cab
TETRA 2Updated plans can be downloaded as appliance is en route
Fire fighters get latest informationFire fighters get latest information
Check database of hazardous chemicalsTETRA 1Text based results from database search
TETRA 2Text and image results from database search
Fire fighters get clearer informationFire fighters get clearer information

TETRA2 brings new capabilities … to AmbulanceTransmit an ECG trace from ambulance to doctor in hospitalTETRA 1Transmit compressed ECG
TETRA 2Less compression used means more details on ECG
More accurate diagnostic for heart conditionsMore accurate diagnostic for heart conditions
Transmit pictures from scene so doctors can predict injuryTETRA 1still images or slow scan video
TETRA 2More detailed video image
Doctors can make more accurate predictionsDoctors can make more accurate predictions

Other Additional Applications of TETRA 2
TETRA 2 Data Application User Benefits
PolicePolice Full mobile dispatch, extending complete control room environment to the field
Greater local control at a major incident site
TransportTransport
Live updates of arrival/departures boards at bus stops
More relevant and accurate information to passengers
Check image database to see manifests, passenger lists etc
Helps reduce smuggling of goods and people
Oil, Gas & Oil, Gas & UtilitiesUtilities
Camera monitoring at very remote locations to check on lone workers
Increased safety for remote workers
Camera monitoring of areas at risk - used to supplement telemetry data
Faster and more accurate understanding of events

TETRA Enhanced Data Service - TEDS
• Backward compatible with TETRA Release 1– Network integration capability
• Flexible data rates and spectrum use– 25, 50, 100 and 150 kHz channels bandwidths– Can trade off data rate, spectrum and range
• Integrated TETRA 1 and TEDS system– i.e. can receive TETRA 1 calls on TEDS channels
• Technology selected for TEDS use – Multi-carrier QAM (Quadrature Amplitude Modulation) in all bands– D8PSK in 25 kHz
High speed packet data service for TETRA enabling faster data rate and higher data capacity
TWC2005 – November 2005November 05 - TETRA World Congress 2005
High Speed Packet Data Deployment
• TEDS will be the solution for mission critical• A range of channel bandwidths available in
the standard– Offer a single TEDS channel at each site, in addition
to TETRA 1 voice channels– Provision channel bandwidth based on number of
users and their data application requirements
• The modulation scheme can adapt to radio transmission conditions

GPRS versus TETRA - Availability
GPRS constraints TETRA 2 benefits
Availability
At times of high voice load there is little or no GPRS service available
– Revenue streams and profit targets dictate data coverage and capacity
– GSM cells often provisioned with dynamic GPRS channels to give priority to lucrative voice services
Users get the level of data service they need
– End user requirements dictate the coverage and capacity in their own private network
– TETRA cells are provisioned with the data capacity to meet
end user’s operational needs
TWC2005 – November 2005November 05 - TETRA World Congress 2005
GPRS versus TETRA - Predictability
GPRS constraints TETRA 2 benefits
PredictabilityGPRS users often see lower throughputs than today’s TETRA packet data users
– GPRS Data bandwidth is shared between many public users
TETRA users get access to the high bandwidths offered by the standard
– TETRA data bandwidth is shared only with users on a private network
TWC2005 – November 2005November 05 - TETRA World Congress 2005
GPRS versus TETRA - Security
GPRS constraints TETRA 2 benefits
SecurityMeets commercial security requirements
Meets Government security requirements, e.g.
–Mutual authentication–Longer keylengths means much harder to decrypt
TETRA: Availability – Predictability - Security
TWC2005 – November 2005November 05 - TETRA World Congress 2005
Typical upgrade to TETRA2
Requirements from all users….
• Maintain GoS (Grade of Service) for voice and any legacy data services
• Increase capacity for new data services
• Easy upgrade
Your expectations for TETRA2
TWC2005 – November 2005November 05 - TETRA World Congress 2005
Things to Remember
• New Spectrum– Maintain present spectrum to keep GoS for
existing voice & data services
• New Terminals for TEDS services– Retain present terminals for existing voice &
data services
In partnership for TETRA2
TWC2005 – November 2005November 05 - TETRA World Congress 2005
Spectrum: Progress has been made…..• ECC (Electronic Communications Committee) has just approved a
Work Item to add support for Wideband technologies in 385MHz – 470 MHz
– 385 MHz – 390 MHz385 MHz – 390 MHz would be the ideal choice for TETRA 2
– reserved for Nato– Sporadically used at present– users need to be very influential
• National regulators are responsible for allocating spectrum – Will Consider the local operating environment– Will Balance requirements from public safety, transportation, etc.
Users need to exert their influence through the MOU and directly to their National regulators
TWC2005 – November 2005November 05 - TETRA World Congress 2005
TETRA 2 takes the lead
The facts of life: • If you already have TETRA you will still be
able to use existing:– Terminals– Application– Services
• When you get TETRA 2 you gain:– Data speed & capacity– New multi media applications– Increased operational efficiency– New possibility to innovate
